80 Phosphate Rocks of South Carolina, 
have lately extended to a capacity of 180,000 cubic 
feet ; and they are now one of the largest manufac- 
turers of Sulphuric Acid in the United States—in fact 
the last chamber which they have erected exceeds 
in size any other in the United States. The whole 
product of these chambers they use to reduce the 
Insoluble Phosphate Rock, into the condition of Solu- 
ble Superphosphate, capable of being taken up by 
growing plants. 
The location of the Works of this Company is 
remarkably fortunate. They occupy the Old Ship 
Yard on Town Creek, about three miles above the 
City of Charleston, where the old frigate John Adams 
was built ; and have a secure dock and deep naviga- 
tion to it for any vessel that can come to Charleston. 
They have also railroad communication from their 
Works to all points, and can therefore receive and 
deliver with economy and despatch. 
The principle upon which this Company is founded 
is, that it will prepare and furnish Guanos of the high- 
est possible grade of fertilizers. They guarantee as 
high a percentage of Soluble Phosphate of Lime as 
twenty per cent., with a sufficient quantity of Ammo- 
nia and Potash to ensure a good fertilizer. Their 
Works and their Guanos are called Etiwan, after 
the Indian name of Cooper River, into which Town 
Creek empties. Besides the prepared fertilizers they 
offer to Manufacturers or Planters who may prefer to 
manipulate their own manures, the Phosphates reduced 
to the condition of Dissolved Bone by the full appli- 
cation of Sulphuric Acid; and thus they enable parties
